New mixed-oxide catalysts shown as viable substitute for platinum catalysts for diesel exhaust aftertreatment

Green Car Congress

Under laboratory-simulated diesel exhaust conditions, this mixed-phase oxide material was superior to Pt in terms of cost, thermal durability, and catalytic activity for NO oxidation. Nanostellar was founded in California in 2004 by scientists from Stanford University and NASA Ames Research Center. Graham, Burtron H. 1225091.

SwRI develops D-EGR demonstrator highlighting fuel-efficient, cost-effective engine; 10% and above fuel economy improvements

Green Car Congress

D-EGR is an engine and control concept that combines fuel reforming to produce hydrogen with high levels of exhaust gas recirculation (EGR) to achieve very high levels of thermal efficiency. liter engine running as a full D-EGR engine from idle to full load, delivering more than 42% brake thermal efficiency with ultra-low exhaust emissions.

This is due to raw, externally premixed fresh charge comprising air, fuel and lube oil being short-circuited into the exhaust during the scavenging process. For one, the [California Air Resources Board] CARB-established limit of HC+NO x emissions in the 7.4 Everything else—pistons, porting and crankcase, bearings, exhaust, etc.—were

ARB researchers evaluate in-use heavy-duty NOx aftertreatment systems, find elevated levels during certain lower-temperature operations

Green Car Congress

A team from the California Air Resources Board (ARB) reports on their evaluation of the in-use emissions performance of four different heavy-duty diesel engines certified to the MY 2010 or interim MY 2010 NO x standards over a wide range of driving conditions in California in a paper published in the ACS journal Environmental Science & Technology.

Michigan State University Receives $2.5M ARPA-E Award to Build Wave Disc Engine/Generator for Series Hybrid Applications

Green Car Congress

In axial-flow configurations, noted Müller and co-authors in a 2004 paper, pure scavenging is a challenging task. Since heat release increases pressure inside the channel, opening the outer channel end generates an outflow of the exhaust gases. Source: Piechna, 2004. Earlier wave rotor implementation were mainly axial flow.
